Revelation 19:7-9

Let us be glad and rejoice and give glory to him. For the marriage of the Lamb is come: and his wife hath prepared herself.

And it is granted to her that she should clothe herself with fine linen, glittering and white. For the fine linen are the justifications of saints.

And he said to me: Write: Blessed are they that are called to the marriage supper of the Lamb. And he saith to me: These words of God are true.
